This complete Dupree Valve assembly includes a hub inlet and outlet that mounts in systems using a permanent outlet hose (typically found in over the road coaches). Used in many MCI bus applications.
NOTE: This is a special configuration. Most private coach owners should use the standard Dupree Twis-Loc Manual Valve found here.
The Dupree Twis-Loc valve was originally developed and marketed as the Owens Valve in 1964, and it has been in production ever since. The Twis-Loc Valve has been installed by many manufacturers during this time such as, Airstream, SilverStreak, Bluebird, Newell and numerous other bus and recreational vehicle manufactures. The Twis-Loc's significant feature is its certainty of operation and valve position with all parts able to be easily replaced.
